This informative publication presents the broad application of nuclear magnetic resonance to many of todays problem areas in agriculture solid state nmr methodology is covered with its applications to the study of intact agricultural matrices such as plant cell walls photosynthetic chloroplast membranes forages wood cellulose and soils. The nuclear magnetic resonance spectroscopy nmr is a nondestructive technique which measures the spin lattice and spin spin relaxation times by means of the radio frequency resonance of protons in a magnetic field to infer for the petrophysical parameters including porosity permeability and free and bound fluids using specially derived . Magnetic resonance in agriculture guest editor pierluigi mazzei nuclear magnetic resonance nmr spectroscopy represents a versatile robust and advanced analytical technique enabling the acquisition of structural multinuclear and conformational information on complex molecular systems. The role of nuclear magnetic resonance nmr spectroscopy in agricultural research is examined in 15 chapters on the following subjects high resolution nmr spectroscopy and its application to in vivo studies 31p nmr studies of higher plant cells nmr studies of metabolism in hypoxic maize root tips and of intact seeds the use of nmr in structural determination of natural plant products high. Nuclear magnetic resonance nmr is a physical phenomenon in which nuclei in a strong static magnetic field are perturbed by a weak oscillating magnetic field in the near field and therefore not involving electromagnetic waves and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus
